July 10, 1956 R. A. GILMOUR SPRAYERS Filed March 13, 1955 INVENToR. A GL MOI/1 F0551? BY g ATTORNEY United States Patent O SPRAYERS Robert A.Gilmour, Somerset, Pa. Application March 13, 1953, Serial No. 342,120 1Claim. (Cl. 299-84) This invention relates to an improved sprayer, andwhile primarily designed and intended for spraying flowers, trees,shrubbery, or like plants and vegetation, with an insecticide oranalogous solutions, it will be obvious that the device may be employedfor spraying any other type of fluid and for any other purposes whereinit is found to be applicable.

Important objects and advantages of the invention are to provide asprayer of the character described, which is adapted for connection witha water hose and operated by the passage of the water therethrough fromthe water hose, which will facilitate and expedite spraying operations,and which embodies novel adjustable means for discharging the solutionin a fanlike spread and spray to cover considerable areas at the sametime.

Further objects of the invention are to provide a device of the classstated, which may be conveniently used by anyone of ordinary skill,which is simple in its construction and arrangement, durable andetiicient in its use, compact, and comparatively economical in itsmanufacture.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the novel construction,combination and arrangement of parts herein specifically described andillustrated in the accompanying drawing, but it is to be understood thatchanges in the form, proportions and details of construction may beresorted to that come within the scope of the claim hereunto appended.

In the drawing wherein like numerals of reference designatecorresponding parts throughout the several views:

Figure 1 is a side elevational View, partly in cross section, of asprayer constructed in accordance with the invention, and illustratingthe connection of the sprayer with a water gun.

Figure 2 is a top plan view of the sprayer.

Figure 3 is a side elevational view, partly n cross section, of thesprayer, and illustrating the attachment of the sprayer with thereceptacle containing the treated spraying agent in fluid form.

Figure 4 is a bottom plan view of the control valve embodied in thepresent invention.

Referring in detail to the drawing, the improved sprayer comprises acylindrical body 1. The body is provided with a transversely extendingpassage 2, which is disposed approximately centrally of the length ofthe body and which is slightly olf side with respect to the axis of thebody.

A nozzle cap 3, including a reduced apertured plug 4 having a screwthread attachment in the inner end of the passage 2, is carried by thebody 1 and is adapted for screw thread connection with the discharge endof the barrel 5, of a water gun 6. The water gun is of the conventionalhand-operated type of construction, is adapted for connection with awater supply hose, and is operable for controlling the ilow of waterthrough the nozzle cap 2.

A horizontally extending discharge tube 7 is revolubly supported in theouter end of the passage 2 and is aligned the discharge tube 7 ;to thelatter by respective pivoting screws projecting part of the spreadermember end of a vertically extending passage 9, which is formed in thebody 1, and which has its wall provided with screw threads. A ball 10 isshiftably mounted in the lower end of the vertical passage 9 and engagesin the annular groove 8 in the discharge tube 7. A spiral spring 11 ismounted in the vertical passage 9 and the lower end thereof seats uponthe ball 10. An adjusting plug 12, having screw thread engagement in thevertical passage 9, seats upon the upper end of the spring 11.

It will be apparent that by the adjustment of the adjusting plug 12 inthe vertical passage 9, the spring 11 may be tensioned to exert therequired pressure upon the ball 10 in the groove 8, to maintain the thedischarge tube in the outer end of the transverse passage 2, whileallowing the frictional rotation of the discharge tube in the transversepassage when required. v

A fluid spreader member 13 is shiftably supported by adjacent to theouter free end of the latter. The spreader member is provided with apair of spaced attaching lugs 14, which engage respective sides of thedischarge tube and which are pivotally connected The spreader member 13projects a considerable distance beyond the outer free end of thedischarge tube 7, and the surface thereof, disposed toward the dischargetube, is flat and of considerable width. The rearwardly is provided withan adjusting screw 16, which may be adjusted to engage the dischargetube to shift the spreader member to various angles from the horizontalto positions to best meet conditions found in practice. the dischargetube will forcibly strike against the flat surface of the spreadermember and thereby cause a fanlke dispersion of the spraying solution.

A vertically extending valve passage 17 is formed in the body 1 andextends throughout the length of the latter. The valve passage isdisposed slightly off side with passage 2 in the body 1. A wall betweenthe valve passage 17 and the transverse passage 2, whereby the valvepassage is communicatively joined with the transverse passage 2 at apoint in the latter intermediate of the spaced adjacent ends of the capplug 4 and the discharge tube 7.

A needle valve 19 is mounted for vertical adjustment in the valvepassage 17, and includes an enlarged valve stem 20, which has a screwthread engagement in the upper part of the valve passage, and which isoperable for vertically adjusting the needle valve in the valvepass-age. A knurled head 21 is removably attached to the upper end ofthe stem 20 by means of a removable pin 22, or in any other suitablemanner, to facilitate the adjustment of the needle valve. The head 21seats upon the top of the body 1 when the needle valve is in the closingposition.

The under face of the head 21 is formed with a plurality of regularlyspaced, circularly aligned, shallow pockets 22 for automaticallyengaging a spring actuated ball 24, which is shiftably mounted in avertically disposed well 25 in the upper end of the body 1. The functionof such ball and pocket engagements is to apprise the operator of theextent of the adjustment made in valve adjusting operations, and furtherto aid in holding the needle valve 19 in the adjusted position.

An apertured valve seating plug 26, for seating the free lower end ofthe needle valve 19, is threadedly engaged in the lower end of the valvepassage 17 and projects a considerable distance beyond the lower end ofthe body 1.

Patented July 10, 1956- plug 4 which is engaged attachment of Thesolution discharging from' The projecting-end o the seating plug extendsthrough the iidv 27 of the receptacle 28 containingl thetreatedfluid 29.T he lid is secured to the seating plug by means of a washer 30, and bya nut 31 which is engaged on the projecting end'of-the seating plug.Ahose 32'L isattached to the projecting endofi theseating plug 26 and'depends intoV the receptacle to the bottom ofthe latter, as shown inFigure 3.

Itewill beapparentv that by advancingthe u eedlevalvey 19 `toseatintheseating plug26 the valve passage'is closed, and that by retractingthe needle valve a slight distance, the passage 17 `is-fully opened tocommunicate with the hose 32; The extentjof' valve needle adjustmentwill ofl course, determineV the amount ot"k treated fluid 29 being addedtoproduce the required sprayingY solution;

Inthe use ofthe improved sprayer, the dischargetube 7 is suitablyadjusted on; itsA revoluble connection with thebody 1; and' thespreadermember 13 is adjusted'by the adjustment of` the adjusting screw 16, toprovide the desired fanlike dispersionof the spraying solution in theselected vertieal,horizontal, or other angular positions.

In the'operation ofthe` sprayer, the forced ow of 'water through thenozzle cap 3, andthrough the transverse passage 2 and discharge tube 7,will create a vacuum draw-ing a-predetermined amount-of thetreated'uid'29 from-the` receptacle-28, throughl the hose 32' andthrough the seating plug 26-and through the valve passage 17 and port18,to mix withand impregnato the Water flowing through the transversepassage 2,V and thereby produce the required spraying solution.

It will be noted'that the improved sprayer can be ernployed forlspraying purposes by using air instead of water tocreate the vacuumtocreate the drawing action required. Whenso using air, the hose 32 would`be extended into a quantity of premixed, solution containing all of thenecessary ingredients for. the purpose intended. Such premixed solutionmay be paint, a detergent, or any other chemical composition or compoundin fluid form.

The present invention providesafmost eicientL device of its kind, whichmay be economically constructed, and successfully employed 'forithe-purposes andin the-manner herein set forth.
